If you have outdoor plans for the weekend you may want to think of alternatives.
The combination of abundant Gulf and Atlantic moisture head of a slow-moving upper-level trough to the west will combine to produce a lot of clouds through the weekend along with some rain and thunderstorms that can occur at anytime. It will not rain every single hour, but long periods without rain seem unlikely. In addition, some of the rain is likely to be on the heavy side. The only sort of good news in all of this is that temperatures will remain well below normal with highs in 70s Saturday and only near 80 on Sunday.
The northern portion of this upper-level trough will move east across the northern part of the country, but not move a lot in the south.
Both Monday and Tuesday are likely to have at least a couple showers and thunderstorms around, but it will not rain as many hours and the best chance for the rain may become more confined to the afternoon and evening hours these days. In addition, some sun will break through the clouds and allow temperatures to warm back up into the middle 80s.
